Format the LUN

[shashi kanth]

I have one LUN , this LUN is part of a shared VxVM diskgroup, and this LUN is attached to a VCS cluster HP-UX boxes.

I re-installed the OS in all boxes, and this LUN is still exposed to this box.

I am not able to use this LUN for HP LVM, because "pvcreate" command shows it is VxVM disk.

I am not able to import the diskgroup in any way.

I am not able to re-initialize this LUN under VxVM.

I would like to simply format this LUN. How can i do this ?


i tried filling /dev/zero by using "dd" command, but still the LUN is having VxVM signature.

Have you tried:

vxdisk -f destroy cXtYdZ

(I'm assuming you use default disk access names)

# vxdisk -f destroy EVA30000_7
VxVM vxdisk ERROR V-5-1-531 Device EVA30000_7: destroy failed:
Disk write failure

So check from eva commandview if this lun (vdisk) is exported as read -only.
